Semiclassical asymptotics and gaps in the spectra of magnetic Schroedinger operators

open access: yes, 2001
In this paper, we study an L2 version of the semiclassical approximation of magnetic Schroedinger operators with invariant Morse type potentials on covering spaces of compact manifolds.

Probing the Black Hole Interior with Holographic Entanglement Entropy and the Role of AdS/BCFT Correspondence

open access: yesFortschritte der Physik, Volume 73, Issue 9-10, October 2025.
The present work, entitled: Probing the Black Hole Interior with Holographic Entanglement Entropy and the Role of AdS/BCFT Correspondence by Fabiano F. Santos, is presented as an investigation of the black hole interior using the Holographic Entanglement Entropy (HEE) and AdS/BCFT Correspondence.

Semiclassical form factor for chaotic systems with spin 1/2

open access: yes, 1999
We study the properties of the two-point spectral form factor for classically chaotic systems with spin 1/2 in the semiclassical limit, with a suitable semiclassical trace formula as our principal tool.

Scattering of NO Molecules from a Graphite Surface: Selectivity of the Rotational Excitation by Inelastic Collisions

open access: yesChemPhysChem, Volume 26, Issue 17, September 10, 2025.
Selectivity and propensity have been emphasized for NO molecules scattered from a graphite surface, employing molecular dynamics simulation alongside a new potential energy surface, including an appropriate treatment of the long‐range interaction, governing the formation of the precursor state, that then reacts with the surface.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

open access: yesContributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime

open access: yesContributions to Plasma Physics, Volume 65, Issue 6, July 2025.
ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

Problem of Nonlinear Conductivity within Relaxation Time Approximation in Noncentrosymmetric Insulators

open access: yesphysica status solidi (b), Volume 262, Issue 7, July 2025.
It is demonstrated that the relaxation time approximation (RTA) for the quantum kinetic equation, a simple method for describing nonequilibrium steady states, has a critical flaw in the longitudinal nonlinear DC conductivity of insulators under weak electric fields.
